Celestial Navigation is a self-teaching book designed for those with a grounding in coastal navigation.
Dealing first of all with the broad concepts of astro-navigation, Gerry Smith takes the reader through the basic skills needed to take sun sights and then plot a position. At each stage of learning there is a summary of the facts as well as exercises to test understanding, before the reader progresses to the next stage.
Gerry Smith's carefully though out course will be greatly appreciated by all those who have been traumatised by the usual complex books on celestial navigation.
This book is in very good condition.
